Obama vows 'unshakeable' support for S.Korea after attack: "US President Barack Obama described North Korea as a pressing threat and pledged 'unshakeable' support for South Korea after the communist state rained a deadly artillery barrage on a border island.
Washington and Seoul agreed to 'coordinate' any response to North Korea after Tuesday's attack, which killed two South Korean marines and sent panicked civilians fleeing the flashpoint Yellow Sea island of Yeonpyeong.
In an interview with ABCNews, Obama would not speculate on military actions that the United States may take in response to the artillery deluge, which has incited global condemnation and depressed financial markets around the world."
